We've been having great fun in Programming By Stealth learning how to use Jekyll to create a website using GitHub Pages. This week Bart goes through the challenge he left us with last time — to add a nav bar to our little static website using Bootstrap 5 along with Jekyll and Liquid templates. Bart had a lot of fun with his solution so it was fun to hear him dust off the cobwebs on Bootstrap. Then we turn to learning about Jekyll's `includes` feature, which is reusable snippets similar to how Te...

We continue our series on making websites using GitHub Pages. Building on our Jekyll knowledge with Liquid templates, we now learn how to create our own theme with Jekyll layouts. The terminology of Jekyll is still tricky, but with some worked examples and a challenge this time, maybe it will start to cement in our brains! You can find Bart's fabulous tutorial shownotes and the audio podcast at pbs.bartificer.net .

In this episode, Bart continues teaching us about GitHub Pages using Jekyll by introducing us to Liquid Templates. Liquid allows us to move from adding static content to our web pages to auto-generated information. It's a lot for one lesson, and some of the terminology is a little weird, but as always, Bart's worked example brings it home. You can find Bart's fabulous tutorial shownotes at pbs.bartificer.net .

In this tidbit episode of Programming By Stealth, Bart Busschots and Helma van der Linden start by reviewing how she took the reins of the XKPasswd project to first convert it from Perl to JavaScript, then to rewrite the web app. After that, she separated the JavaScript library from the web app code. This episode is primarily walking through exactly how she accomplished that split. And now XKPasswd is officially out of beta and available at xkpasswd.net You can find Helma's fabulous tutorial sho...

Last time we learned how to install Ruby, install Bundler, install Gems, and build a very simple website using Jekyll as our static site generator into GitHub. In this installment of our Jekyll miniseries, Bart explains Jekyll's build process which is mostly automated by how you name things and the content of the files you create (like adding YAML front matter.) Then we spend some quality time bemoaning how the Jekyll developers reuse the word "assets" to mean two different things. Bart avoids s...

In our miniseries on GitHub Pages, we learn how to create a basic Jekyll site. To do this, we must install a modern version of Ruby, install its Gem Bundler, create a little placeholder site, and then serve Jekyll to view our site locally. We push it to GitHub where the GitHub Actions we learned about last time do their magic and create a real website all for free. But we didn't stop there. One of our goals is to create our own theme, and to build on what we get with Bootstrap. We actually downl...

Way back in September of 2022, Bart finished off the Webpack miniseries by leaving it as an exercise for the student to deploy their web apps to GitHub Pages. Bart closes that circle in this installment while teaching us how to use GitHub Actions. We learn about workflows, jobs, steps, events, and runners. Bart includes great tables in the shownotes of the terminology, so we now have a handy reference guide for making our own YAML files to run GitHub actions. You can find Bart's fabulous tutoria...

In Programming By Stealth this week, Bart has started a new miniseries to teach us how to use GitHub Pages to create a website (for free.) In PBS 175, he starts by explaining what Static Site Generators (like GitHub Pages) are, and the pros and cons vs. a more traditional content management system like WordPress. Neither are wrong, they just solve the same problem in different ways. He then gives us the framework for the tools we'll be using and lays out the next few lessons where we'll get in a...

As promised, we're back with part 2 of the Powershell Teaser. We pick up where we left off, starting with learning about parameter definitions and the advantages such a structured language affords us, including automatically generated help files and error checking. Bart updated the shownotes to include valuable resource links to take your PowerShell to a higher level. We walk through our plan for 2025, where Bart is going to teach us about GitHub Pages (which power the Programming By Stealth sho...

Bart Busschots is enamored with the open source shell from Microsoft called PowerShell. His goal was to give us a teaser on this modern shell but there was enough material in his shownotes that we're recording the audio in two halves. Feel free to read ahead in the shownotes if you like, or you can wait till the second installment to read the rest. In this first half, we learn about how Bart begrudgingly started using PowerShell and what made him become such a fan. He walks us through the philos...

In a very unusual Tidbit episode of Programming By Stealth, Allison interviews NosillaCastaway and Programming By Stealth student Steve Mattan about how he's running Large Language Models locally on his Mac. He pulls this off using a series of open source tools, starting with Ollama for the models from the command line, and then Enchanted to give him a nice GUI. He explains how he's integrated the local LLM into VSCode for his coding, and how he uses Keyboard Maestro to launch all of this at onc...

In this installment of Programming By Stealth, Bart completes his miniseries on Git Submodules. Last time he created an imaginary company with three developers and went through three relatively simple scenarios where Git submodules were implemented. In this finale installment, he takes it up a notch in complexity and we actually get to push submodule changes. The path is fraught with danger and I get stuck on the very last scenario but Bart wouldn't let me give up and eventually helped me unders...

In PBS 172 Bart Busschots explained what Git submodules are and the kinds of problems they solve. In this practical lesson, he walks us through three scenarios where we actually get to type in Git commands to learn how the process works. We get to pretend we're in a small web app business where company branding is important. In the first scenario, we're a new developer joining an app team and we have a repo that already includes the branding submodule. In the second scenario, we're a seasoned de...

Bart takes us back into our Git miniseries to explain Git submodules, which are essentially nested Git repos. After we learn what they are, he explains why nesting is needed. Then he takes us through three use cases as a way of illustrating the kinds of problems Git submodules can solve. You can find Bart's fabulous tutorial shownotes at pbs.bartificer.net .

In ye olden days, iOS kept everything sandboxed in a way that apps weren't allowed to reach outside of their own data to open individual files. But with the aptly named Files app, and an API to allow a human to do the picking, apps can now open files directly on iOS. This "innovation" allows us to have a Git client on iOS and have it use a linked repo that's stored in the Files app. This means we can use any text editor we like to open the repos files for editing. In this tidbit episode of Progr...

We're back from our summer hiatus (actually scheduled for the first time ever instead of accidentally happening!) In this week's episode, Bart takes on the task of explaining the philosophy behind why having a framework for software development is useful and even crucial as projects get bigger and more complex. We chose this topic because the XKPasswd project has already started using a framework called Model View Controller. We get the barest understanding of MVC in this explanation from Bart, ...

In this special tidbit installment of Programming By Stealth, Helma van der Linden joins Allison to walk through how she solved a real-world problem using jq. The problem to be solved was a need to analyze the installed applications on her Intel-based Mac before migrating to her new Apple Silicon Mac. She used a built-in Terminal command to access System Information to create a JSON file, and then used a series of jq filters to remove data she didn't need, and format what she kept into human-rea...

In this second (and final) installment about YAML, Bart teaches us who to write multi-line strings and how not to write multi-line strings. He teaches us about String Blocks which is a bit head-bendy but allows you to write human-readable strings and also tell YAML what to do with empty lines and white space. After that slightly heavy lift, we learn about how to write much simpler-looking Sequences and Mappings than the way we learned in our introduction to YAML in PBS 168. It's really nifty how...

In Programming By Stealth, we've completed our series on the jq language and now Bart Busschots brings us a two-part miniseries about the YAML data format. He takes us through the history of data formats we've "enjoyed" such as fixed-width text files, Comma Separated Value files, through to JSON and XML. All of them had their place in history but also had their downsides. YAML promises to be human-readable (yay) and computer-readable (also yay.) Once we're bought into how YAML is the data format...

It was actually bittersweet for Bart and me this week as he taught the final installment in our series of Programming By Stealth about jq. As Bart says partway through our recording, he thought this would just be a few episodes but it took 13 episodes to go through everything Bart thought was fun about this deceptively simple programming language. This final installment in the jq series covers querying nested data structures with the `recurse` command. One of the really fun parts of the episode ...

In this penultimate jq episode of Programming By Stealth, Bart introduces us to three new ways to process arrays and dictionaries without exploding them first. I know that sounds crazy – we've always exploded our arrays first. He teaches us how to use the `reduce` operator which lets us take an entire array or dictionary and reduce it down to one thing. The `map` function lets us process every element in an array (or or values in a dictionary) and return a new array. Finally, `map_values` lets u...

In this installment of Programming By Stealth, Bart explains why jq is uniquely designed not to need variables (most of the time) and then explains how to use them in the few instances when there's no other way. It's really a fairly straightforward lesson as Bart sets up some clear examples and solves them with some simple variables. It's one of my favorite episodes because the problem is clear and the solutions are clear. It really shows off how clean jq is as a language. You can find Bart's fa...

In our previous episode of Programming By Stealth, Bart Busschots taught us how to create lookup tables with jq from JSON data using the `from_entries` command. Just when we have that conquered, this time he teaches us how to do the exact opposite – disassemble lookup tables. I think this was a really fun lesson because taking data apart, reassembling it the way you want and then putting it back together again is a great way to really understand what we're doing with jq. I got much more comforta...

In this episode of Programming By Stealth, Bart Busschots as usual works through his solution to the challenge from last time, and as usual I learn a lot more about how to use jq to solve problems. He takes a bit of a detour to explain a fun email we got from Jill of Kent in which she explained the vast number of headaches you'll run into when trying to alphabetize names no matter the language. Then we buckle down and learn about how to make tradeoffs between speed and efficiency of resources, a...

Bart Busschots is back to teach us how to alter arrays and dictionaries in JSON files using jq. Bart went through his challenge solution on cleaning up the Nobel Prize database and I learned a lot from it. Maybe he'd already taught all of it to us before but I sure wouldn't have been able to put the pieces together. For the new content, we learned how to alter arrays. We mastered sorting and reversing, how to add and remove elements, how to deduplicate the values within, and how to flatten even ...

In this week's episode of Programming By Stealth, Bart continues to expand our knowledge on how to use jq to query and manipulate JSON files. We learn how to use mathematical operators on data in our JSON files along with fun functions like floor and absolute value. I even contributed some to the learning by showing examples of how `ceil` (for ceiling), `floor`, and `round` produce curiously different results when operating on negative decimal numbers. We move onto learning about both plain assi...

In this week's installment of Programming By Stealth, Bart Busschots teaches us how to use jq as a programming language. Before we get into the new stuff, Bart takes us through his solution to the challenge, and I have to say I was pretty chuffed when he said my solution to the extra credit portion was more elegant than his. To be fair, it took a buddy programming session with him for me to get the _first_ part of the challenge figured out. When we got into the programming language part of the l...

In this very meaty episode of Programming By Stealth, Bart Busschots teaches us how to build data structures using jq with JSON files. We're not just querying existing data, we're rebuilding the data the way we want to see it. We learn how to build strings with interpolation, which I find is a very odd word to describe the process. It's really like concatenation in Excel, but maybe that's just me. We build arrays using jq, and even convert between strings and arrays with the `split` and `join` c...
